Overall the subtle outlines and "thin" font makes it difficult to pick out what you need/want to do, especially at a glance in bright light. Overall more contrast and delineation would allow a faster more accurate interaction.
Further, eliminating metaphors in the "look" of an app built for a particular market segment can be problematic. It is well-known that these market segments will only shift away from the familiar way of doing things if the app is designed around the professional user's tried and true methods. Many times these UI/UX approaches are counter intuitive causing the user to get frustrated both in the amount of time to learn how to use it while also trying to adapt to an unfamiliar.

HEY RETARD! If they listened to all their customers...their company would go to shit. Let's be real, all you guys have something to complain about, but you got nothing to show. Before you act like your words matter, get a degree, get a job, maybe advance to working with Apple. Only then does your words matter. As of now, you're all just a bunch of whiny mongers. Grow some balls and accept what comes to you. It's like Facebook, when they rolled out their new interface....every f*cking bitched like dogs on heat. Now, everyone is cool with it. So, stfu and get use to the firmware.

The people who made the previous UI probably had a degree and obviously a good job but these new designs could have been created in MS Paint while the previous designs required nothing less than Photoshop or something at that level. I'm sure these guys love having less work to do because they're certainly not concerned about being proud of their products.
